Windows shuts down!!!

Step 1:
Laptop computers can be wonderful devices, except when the need to troubleshoot arises. Acer laptops are no different. A quick way to fix many problems with an Acer laptop running Windows is to reset it to factory settings. Resetting your Acer laptop to factory settings can eliminate slow operation, registry problems, virus problems and spyware issues. What's more, a factory reset of your laptop may reduce the need for a full reinstallation of Windows.

Back up all necessary data to an external device such as a disk, flash drive or hard drive Make sure all programs are closed and shut down your Acer laptop. Detach any external hardware such as an external hard drive or printer. Press the Power button to boot your Acer laptop. Press "Alt-F10" on your keyboard when the Acer screen appears at the start of the boot-up process. Wait a moment while Windows loads the reset files. Select "Restore System from factory default" in the Acer eRecovery Management window. Click "Next" on the next screen to continue. Click "Next" on the following destination information window. This will pop up a notice telling you that resetting your Acer laptop will erase all data and restore the laptop to its original settings and configuration. Click "OK" in the notice window to proceed with resetting your Acer laptop. Wait while your Acer laptop is reset to factory settings.

first make sure that your video card driver is installed.. then after installing install the latest version of flash.

You could try unplugging your laptop and taking the battery out, wait a few minutes put the battery back in, then plug it back in to the wall receptable, if you were working on something you wanted to save when this happend it might not keep any of the information, you should be able to boot it back up normally.

Hi! It appears that possibly your hrad drive isn't set properly in the caddy? with the laptop powered down and disconnected locate the hard drive cover pop out the two locating screws and carefully move the caddy/hard drive BEWARE as the drive has fragile pins at the opposite end where you opened, hopefully little sliding pressure should remove. Check the retaining screws around the caddy (You'll need a small torx/philips screw driver for this) if all tight replace gently.
If you are uncertain I would recommend a technician check it for you.
Good Luck!

Try tapping the F5 or F8 key (could be either one) right after you power up. This should take you to a short text message with a couple of choices to continue; you'll find the Safe Mode option there.
